Letters Patent No. 98,998, dated Janua'ry 18, 1870.

IMPROVED TONGUE AND THILL-COUPLING.

' The Schedule referred to in these Letters Patent and making part of the nine.

T 0 all whom it may concern Be it known that I, JAMES I. PnoK, of Deansville,

in the county of Oneida, and State of New York, have coupling which shall not only be easily and quickly detachable, as well as simple, strong, and cheap, but whose main feature shall be the construction, whereby a'donble bearing-surface is formed, thereby'insuring much greater safety of connection and durability of parts than has heretofore been the case.

In the accompanying drawing- Figure 1 is a perspective top view of a coupling, constructed according to my invention.

Figure 2 is an end view of the'same.

Similar letters of reference indicate corresponding parts. I

This thill-coupling is formed of two parts, A andB. The part A (or the clip is rigidly attached to the axle of the buggy, and is a plate of metal, withits outer end coiled to something like a half circle, forming a hook for receiving the draught. There is a vertical slot through the hook, which I extends back to receive the thill-iron B.

The part B and the part D of the thill-ironare both fiat, and the planes of their flat surfaces stand at a right angle with each other.

The breadth of the foot D (or the length of the are E) is sufficient to allow of any required vertical motion in the thills, and still keep the T in its place in the hook. To detach the thills, it is only necessary to raise them, so that the are E will leave the slot, when the foot can be readily lifted up through the slot. For attaching the thills, they are raised in the same manner, and, when they are brought down, and the circle E enters the slot, the T findsits place in the hook, and the coupling is complete.

Thus it will be perceived, by slotting the plate Aat its outer end, and curving the forks, thus formed, around the, pivot-bolt O, a double hearing or connection is formed, whereby, if onepart of the forkor bolt should be broken, or in any way injured, the other will remain intact, and the coupling still perform its function. Furthermore, it is evident that the coupling will last double the time of those having but single bearing-surface.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent-- The part A of the coupling, slotted longitudinally at its outer end, to receive the foot D of the thill-iron B, and having its fork ends oiu'ved partially around the ends of the pivot-bolt 0, whereby a double bearing-surface is formed, as and for the purpose specified.
